I have been wondering about that support, too - the one at the top of the left-hand column, right? I think that the track will roll to the left 180 deg coming down out of the tophat and then reverse roll 90 deg to the right before pulling out at the bottom into the brake run. The only other thing I can think of is that the track could leave the tower right after the tophat into additional elements and then return to the tower at that oddly positioned support. I think the first theory is more likely.
